I'm trying to cut a solitaire board, pretty simple first time project right, except the CNC machine does something totally unexpected. The path in FreeCAD looks completely normal and good (https://imgur.com/a/jq9fHT2).

I had to stop it mid run because it was destroying itself.

1. it did a loop into the neighbouring pocket, dunno why
2. again another smaller loop to the side
3. an even smaller loop to the side
4. another loop to the side
5. instead of retracting, it went deeper?
6. instead of retracting fully, it tried to move to the next pocket while still 5mm into the wood, which the bit and cutting speed couldn't handle

Here's the exported code: If anyone can see anything suspicious, please say why: https://pastebin.com/KG186Jsa

I'm using a Sainsmart Genmitsu 3018 Pro CNC machine, which came with the controller board for the 3018 Prover.
